The Colon’s Ended. Do We Need a Full Stop?

Colon Avenue is minor suburban road intersecting Monterey Boulevard traveling south, and terminating at the baseball field of the City College of San Francisco. A colon was an ancient punctuation mark separating two clauses where the second expands upon the first but that is lost in history. Was Colon’s Last Stand in a College classroom here?

We don’t subscribe to this because this sign looks brand new, and there are no language professors weeping at its foot. We have heard San Francisco has a vibrant population, but we are reticent about making it a butt for jokes. Colon Avenue remains an unexplained mystery, and a convoluted path that twists and turns towards the truth.
